Three-Dimensional Analysis of Voids in AM60B Magnesium Tensile Bars Using Computed Tomography Imagery

Description: In an effort to increase automobile fuel efficiency as well as decrease the output of harmful greenhouse gases, the automotive industry has recently shown increased interest in cast light metals such as magnesium alloys in an effort to increase weight savings. Currently several magnesium alloys such as AZ91 and AM60B are being used in structural applications for automobiles. However, these magnesium alloys are not as well characterized as other commonly used structural metals such as aluminum. … more

The Design and Analysis of Salmonid Tagging Studies in the Columbia Basin : Volume XVII : Effects of Ocean Covariates and Release Timing on First Ocean-Year Survival of Fall Chinook Salmon from Oregon and Washington Coastal Hatcheries.

Description: Effects of oceanographic conditions, as well as effects of release-timing and release-size, on first ocean-year survival of subyearling fall chinook salmon were investigated by analyzing CWT release and recovery data from Oregon and Washington coastal hatcheries. Age-class strength was estimated using a multinomial probability likelihood which estimated first-year survival as a proportional hazards regression against ocean and release covariates. Weight-at-release and release-month were found t… more

Monitoring and Evaluation of Smolt Migration in the Columbia Basin : Volume VII : Evaluation of the Compliance Testing Framework for RPA Improvement as Stated in the 2000 Federal Columbia River Power System (FCRPS) Biological Opinion.

Description: Using the pre-2000 reach survival probabilities reported in the 2000 FCRPS Biological Opinion (BO) for three selected stocks: yearling and sub-yearling chinook and steelhead, power curves were constructed for each of the two statistical hypothesis tests suggested in the BO. These power calculation results were interpreted in terms of the ability of the statistical tests to correctly identify the true states of recovery (i.e., fail or succeed in fulfilling RPA expectations). The proposed one-sid… more

Simulation of Tailrace Hydrodynamics Using Computational Fluid Dynamics Models

Description: This report investigates the feasibility of using computational fluid dynamics (CFD) tools to investigate hydrodynamic flow fields surrounding the tailrace zone below large hydraulic structures. Previous and ongoing studies using CFD tools to simulate gradually varied flow with multiple constituents and forebay/intake hydrodynamics have shown that CFD tools can provide valuable information for hydraulic and biological evaluation of fish passage near hydraulic structures. These studies however a… more

Physical Characterization and Steam Chemical Reactivity of Carbon Fiber Composites

Description: This report documents experiments and analyses that have been done at the Idaho National Engineering and Environmental Laboratory (INEEL) to measure the steam chemical reactivity of two types of carbon fiber composites, NS31 and NB31, proposed for use at the divertor strike points in an ITER-like tokamak. These materials are 3D CFCs constituted by a NOVOLTEX preform and densified by pyrocarbon infiltration and heat treatment. NS31 differs from NB31 in that the final infiltration was done with l… more

Deep Borehole Instrumentation Along San Francisco Bay Bridges - 2001

Description: This is a progress report on the Bay Bridges downhole network. Between 2 and 8 instruments have been spaced along the Dumbarton, San Mateo, Bay, and San Rafael bridges in San Francisco Bay, California. The instruments will provide multiple use data that is important to geotechnical, structural engineering, and seismological studies. The holes are between 100 and 1000 ft deep and were drilled by Caltrans. There are twenty-one sensor packages at fifteen sites. The downhole instrument package cont… more

Technology Transfer to U.S. Independent Oil and Natural Gas Producers

Description: The Petroleum Technology Transfer Council (PTTC) continued pursuing its mission of helping U.S. independent oil and natural gas producers make timely, informed technology decisions. PTTC's Board made a strategic decision to relocate the Headquarters (HQ) office from Washington, DC to Houston, Texas. Driving force behind relocation was to better connect with independent producers, but cost savings could also be realized. Relocation was accomplished in late December 2000, with the HQ office being… more

Conbined noble gas and stable isotope constraints on nitrogen gas sources within sedimentary basins. Final report for period 15 March 1996 - 14 March 1999 extended to 14 March 2000

Description: Nitrogen is one of the major non-hydrocarbon gases found in natural gas reservoirs. The objective of this work was to combine the information available from both noble gas and stable isotope systematics to understand the origin of nitrogen and related gas sources, transport behavior, and mass balance within natural gas reservoirs and sedimentary basin systems. The goals achieved are summarized under the following headings: Noble gas and stable isotopes in nitrogen-rich natural gases; Noble gase… more

DATA MINING AT THE NEBRASKA OIL & GAS COMMISSION

Description: The purpose of this study of the hearing records is to identify factors that are likely to impact the performance of a waterflood in the Nebraska panhandle. The records consisted of 140 cases. Most of the hearings were held prior to 1980. Many of the records were incomplete, and data believed to be key to estimating waterflood performance such as Dykstra-Parson permeability distribution or relative permeability were absent. New techniques were applied to analyze the sparse, incomplete dataset. … more

Recovery and Sequestration of CO2 From Stationary Combustion Systems by Photosynthesis of Microalgae, Quarterly Technical Report: January-March 2001

Description: Most of the anthropogenic emissions of carbon dioxide result from the combustion of fossil fuels for energy production. Photosynthesis has long been recognized as a means, at least in theory, to sequester anthropogenic carbon dioxide. Aquatic microalgae have been identified as fast growing species whose carbon fixing rates are higher than those of land-based plants by one order of magnitude. Physical Sciences Inc. (PSI), Aquasearch, and the Hawaii Natural Energy Institute at the University of H… more

Analysis of Depth-Sensing Indentation Tests with a Knoop Indenter

Description: The present work shows how data obtained in a depth-sensing indentation test using a Knoop indenter may be analyzed to provide elastic modulus and hardness of the specimen material. The method takes into account the elastic recovery along the direction of the short axis of the residual impression as the indenter is removed. If elastic recovery is not accounted for, the elastic modulus and hardness are overestimated by an amount that depends on the ratio of E/H of the specimen material. The new … more
